The following Python programming code illustrates how to perform an inner join to combine three different data sets in Python. For this, we can apply the Python syntax below: data_merge1=reduce(lambdaleft,right:# Merge three pandas DataFramespd.merge(left,right,on=["ID"]),[data1,data2,dat...

In general Python will be considerably faster and there are also optimisations for big integers. For example running '%timeit fib(100000)' takes just 5.25ms to return all 20899 digits. In Excel however much of the gains will probably be lost in data transfer so I think lambda solutions are...

NOTE: there is no need to create an additional LAMBDA function, since all the functions involved in FIBO work with arrays, i.e.: FIBO(SEQUENCE(1000)) which should be even faster than FIBO_SERIE which uses BYROW. I tested it for the first10KFibonacci numbers and almost instantaneously, the...
